1. Appearance: Qiao's golden leg is usually composed of high-heeled shoe soles, thick uppers and heel height on the outside, with a wide arch, while the silver leg is mainly formed by folding the soles of the thighs and calves, with a narrow arch. In addition, the golden leg is usually made of leather, while the silver leg is connected by achilles tendon.
2. sense of use: due to the different arch widths, the golden leg can make the whole sole touch the ground, while the silver leg mainly makes the heel touch the ground. Golden leg can effectively reduce the pressure on the sole and relieve the symptoms of plantar fasciitis, and at the same time, it can also increase the stability of knee joint and reduce knee joint injury. However, because the arch of the silver leg is relatively low, it will make the heel touch the ground when walking, thus increasing the pressure on the knee joint, and at the same time increasing the load on the ankle joint, which is easy to cause knee joint injury.
